(Cl. 355-71) This invention relates in general to an anatomior shape after the same or a portion thereof has cal demonstrating device, but more specifically to been distorted. a device for use in the demonstration of diseased In the present form of the invention the body condition of the mouth, such as pyorrhea, Vinportion is in the shape of one of the gums and cents angina (commonly known as trench palate 11 of the human mouth.

Figures 3, 7 and 3.

the lower end of the tooth is inserted one end of a tube 30 which is in register with the channel 29. The inner end 31 of the tube 30 projects into the chamber or cavity 13 to be submerged in the liquid 16 within the cavity.

In each form of the invention and in use, the liquid 16 as shown in Figures 3, 4 and 6, and the liquid 25 in the cavities 22 in the form of the invention shown in Figures 7 and 8, is adapted to be forced through the respective passages or channels to the outer surface of the body, and this may be accomplished in one of several Ways.

As shown in Figure 4, one of the walls 32" of the chamber 13 may be in the form of a web or of a thickness considerably less than the thickness of the remaining Walls so as to allow the same to be easily deflected or distorted when pressure is applied thereto.

The normal position of the form of the inven tion shown in Figures 3 and 4 is illustrated in Figure 3, and in use the device may be grasped between the thumb and forei'lnger of the hand, with the forenger resting against the wall 32 While the thumb rests against the portion 11 of the device, representing the palate. By exerting pressure upon the body portion with the thumb and forefinger the wall 32 will be deected, with the result that the liquid 16 in the chamber 13 will be forced through the tubular members 14 to be discharged through the ends 15 of the tubes. This will demonstrate the action of the fluid or pus formation in the human mouth under a diseased condition of the mouth, as the liquid will be forced through the tubes so that it will have the appearance of oozing or flowing out of the gums at the base or the diseased por tion of the tooth, as Well as through the gum at points remote from the teeth, according to the Y number of tubes and the location of such tubes.

As soon as pressure of the thumb and forenger is relieved, the suction created in the chamber 13 will cause the liquid which has been discharged to flow back into the chamber.

In this form of the invention, the body portion may be also 'constructed of such a material and 'of such resiliency that when the device is resting fiat upon a support such as a table or the like, 'the Vbody portion may be temporarily distorted sufficiently to cause the uid in the chamber'or cavity 13 to be ejected through the tubes 14 by a pressure exerted upon the tips of one or more'of the teeth 21. j

In the form of the invention shown in FiguresA 7 and 8, the action will be the same as described in connection with Figures 3 and 4, While in the form of the invention shown in Figure 6, the fluid will flow through the tooth 23 under the same yaction instead of alongside of the tooth as de'- scribed in connection with the thumb shownin In the form of the invention shown in Figure 9, there is disclosed a means whereby the action of the fluid in an abscessed condition of the tooth may be readily seen. In this form of the invention the numeral 33 designates the body vportion of the device, and 34designates teeth. One of the vteeth is provided with a channel or'passage 35 extending therethrough, and in this form of the invention the lower portion of the tooth is removed as at l36, and a cavity 37 with which the channel 35 in the tooth communicates, is arranged at the root of the tooth, the cavity 37 containing liquid and representing an ulcer formed at the base of the tooth. The open sideof the channel 35 as well as an open side ofthe cavity 37 is closed by means of' a transparent closure 38, preferably in the form of glass secured and held in position with respect to the body 33 in any desired or suitable manner.

In this form of the invention When pressure is exerted upon the top of the tooth containing the top of the channel 35, the liquid in the cavity 37 will be forced through the channel 35 and out of the open channel at the top of the tooth. The resiliency of the body portion 33 will permit of such action of the teeth and when pressure of the finger on the tooth is relieved, the inherent resiliency of the body portion 33 Will cause the tooth to return to its normal position, and at the same time the liquid which has been forced into the channel 35 will be drawn back into the charnber or cavity 37.

With this invention it will be manifest that any diseased condition of the mouth may be readily demonstrated, and While the preferred forms of the invention have been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, Within the scope of the claims, Without departing fromfthe spirit of this invention.
